Verbier/La Tzoumaz - New Eateries?

Verbier/La Tzoumaz has four new on-mountain eateries opening this year - I wondered if anyone had visited them yet? I've got various relatives going out to our apartment there, and would like to update my Local Guide. They are as follows:

The Igloo at Mt.Fort, and in the La Tzoumaz area:
The Snow Bar at Etablons by the road tunnel.
The Chalet Blanc just below the Savoleyres summit
The Pentadecagonal Bar at Croix de Coeur

Thanks
